To all whom it may concern:

Be it known that I, CONRAD MILLER, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Dumping- Bodies for Vehicles; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in dumping-bodies for vehicles. The end portions of my improved wagon-body have bottoms downwardly inclined from their outer extremities, while the sp ace between these two inclined bottom portions is normally closed by a tiltable chute, either extremity of which is adapted to be lowered to allow the entire contents of the wag0n-body to be-discharged therefrom on either side, as may be desired. Each extremity of the tiltable chute projects a short distance from the sides of the wagonbody on each side and with it is connected suitable attachments whereby either extremity of the chute may be locked in the raised position or released and allowed to fall to the dumping position, as circumstances may require. When this tiltable chute is in the raised or elevated position, it forms the central part of the wagon-body bottom and cooperates with the inclined ends of the bottom to form the complete bottom of the wagonbody. These inclined ends are hinged and adapted to be lowered to the horizontal position or to a position in the plane of the central part of the wagon-body bottom when the latter is raised. l/Vhen the inclined bottom end portions are lowered or when either of them islowered, the contents of the wagonbody may be shoveled out of it in the ordinary way when it is not desired to dump the contents of the wagon-body by moving the tiltable chute to the inclined position.

Having briefly outlined my improved construction, as well as the function it is intended to perform, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In the drawing, Figure 1 is a side elevation of my improved dumping wagon-body, the

tiltable chute being lowered to the dumping position. Fig. 2 is a similar view with the chute raised to the closed position. Fig. 3 is a vertical longitudinal section taken through the wagonbody. Fig. 4 is a vertical crosssection taken on the line 4 4, Fig. 1. Fig. 5 is an underneath view of one of the hinged end sections of the wagon-body bottom, illustrating the means for looking it in the raised or inclined position.

The same reference characters indicate the same parts in all'the views.

Let A designate the opposite vertical sides of the wagon-body, whose bottom is composed of two end parts (each designated A) and a central part, (designated A These end parts normally occupy an inclined position, as shown at the right of Fig. 3; but they are hinged at their lower extremities, as shown at A and are adapted to be locked in the inclined position by means of a lever B fulcrumed on the under side of the part A, as shown at B. Pivotally connected with the lever at points B on opposite sides of its fulcrum are two locking-rods B which engage guides B having ways which register with recesses B formed in the opposite sides of the wagon-body and adapted to receive the outer extremities of the rods B when the lever is shifted to the position shown in Fig. 5. When, however, it is desired to lower the bottom section A to the position shown at the left in Fig. 3, the lever B is shifted to the reverse position, or rather to a position causing its inner extremity to engage a stoppin B, when the locking rods or pins B Wlll be moved inwardly sufiiciently to disengage them from the recesses of the wagon-body sides, whereby the part A may be lowered to the horizontal position, as shown at the left in Fig. 3. It may be assumed, however, that both of the bottom sections A are in the inclined position, as it is supposed that the wagon-body will be used more with the said sections in the inclined position than in any other way, since it is more especially intended as a dumping-body, whereby as the chute A forming the central part of the bottom, is lowered at either end the entire contents of the body may be allowed to escape at the side as heretofore explained.

The manner of o erating the tiltable chute A will now be escribed in detail. This chute forms the central portion of the wagonbody bottom, as heretofore explained, and is adapted to close the central opening between ITO the two inclined parts A of said bottom. site sides 01" the chute or central bottom see- This chute or central wagon-body bottom section is suspended at opposite sides ol the wagon-body by means 01'' chains 1), two on each side. The lower extremities of the chains are connected with hooks D, movably attached to eyes D secured to the chute just outside of the vertical sides of the wagonbody. The upper extremities of the two chains on each side of the wagon-body are connected with levers E and F, respectively. These levers are provided with curved or segmental portions E and 1 respectively, whose peripheries are grooved to receive the chains, the latter being attached to the upper extremities of the said segmental parts or the levers. The two levers are so located that there is constantly a vertical upward pull on the chains, whereby the latter are kept in a perpendicular position during the operation of raising and lowering the chute, thus preventing any tendency toward side strain or friction on the chute. The levers E and l are connected at points E and 1*, respectively, by a connecting-rod G. The lever F is provided with an extension F above or beyond a point 1 and. this extension is connected, as shown at H, with one extremity of a rod H, whose opposite extremity is connected, as shown at H, with a hand-lever H provided with a locking-pawl 1'1 engaging a quadrant H This lever is l'ulcrumed at its lower extremity, as shown at H, and the dog H is controlled by means of a pivoted handpieee 11 pivotally connected with the lever. This part 11 is connected with the dog H by a rod 11 This is an ordinary lever and quadrant construction. it will be understood that both sides of the wagonbody are equipped with a set of the devices just explained, and since the operating devices for the tiltable chute are the same on. both sides of the wagon a description of the wagon on one side is suflicient.

it will be observed that when the chute A is lowered at one end, as best illustrated in Fig. l of the drawing, the supporting de vices connected with the opposite end form, in effect, a hinge, permitting the tree upward-and-downward movement of the chute in a manner that will be readily understood.

For convenience in dumping or discharging the contents of the wagon-body the chute is provided with end extensions A, having upwardly-extending side pieces composed of metal plates A extending across the bottoms of the end extensions and having their extremities A turn upwardly on opposite sides of the said extensions. These upwardly-turned parts prevent the material from falling oil from the side of the chute as soon as they leave the wagon-body, and by means of them the material or contents of the wagon-body may be discharged into any 1 l 1 l l tion A" of the wagonbody are located de pending parts 1, which extend downwardly far enough to prevent the nntterial from passing over the sides of the chute within the vertical planes of the sides of the wagon body. These parts .l. also serve as guides l'or the chute during its upward-and-downward movement.

The ends of the \\"agonbody are provided with narrow vertical sections J, engaging ways J, lormed on opposite sides ol the wagon-lmdy. These vertical end sections (l rest upon the outer extremities of the inclined hinged. sections A and may be removed soon as the inclined sections are lowered to the horizontal position. At the extremities of the wagon-body are located cross-pieces K, which form a sup ort tor the sections A when lowered to the horizontal position.

The parts designated l. and M in the drawing constitute the rear and front axles ojl the vehicle, respectively, to which it may be assumed my improved wagon-lmdy is applied. ln Figs. 1 and 2 the wheels ol the vehicle are indicated by dotted lines.

The wagon-body provided on opposite E sides of the depending parts l with cross-bars N, which give additional strength and durability to the structure.

Attention is called to the tact that the levers E and F are ifulerumed at l .1 1, respectively, while the periphery of the segmental parts E and F of the said levers l'orm the arcs of circles struck from the fulcrum-points E as centers. This is necessary in order that the point from which each chain pulls may always be directly above the point at which the lower extremity ol the chain is connected with the chute, whereby all tend ency toward side thrust and friction is overcome.

From the foregoing description the use and operation of my improved dumpingbody for vehicles will be. readily understood. Assuming that the chute A is in the closed position, as shown in Figs. 2 and 23 of the drawing, and that the inclined bottom sections A are in the position shown at the right of Fig. 3 and as indicated by dotted lines in Figs. 1 and 3, it it. is desired to dump the contents of the wagon-body the handlever 1T on one side is thrown from the position indicated in Fig. 2 to that indicrted on the nearest side of Fig. 1, whereby the levers E and F are shifted sulliciently to allow one end of the chute A" to drop downwardly to the dumping position. lt will then be understood that the entire contents ol the wagon-laid may be discharged at the side ol the wagon-body, where the protruding extremity of the chute is lowered. l t will be understood that while the one extremity ol convenient receptacle or location. On oppothe chute is lowered, as shown in Fig. 1 ol the drawing, and the operating or manipulating devices are correspondingly actuated the said devices connected with the opposite extremity of the chute are retained in their normal or locking position. If it is desired to shovel out the contents of the wagon-body in the'ordinary way, the tiltable chute or central part A of the wagon-body bottom is kept closed and one or both wagon-body parts A are lowered to the horizontal position, the upper end sections J being one or both removed, as may be desired. When this is done, it is evident that the structure may be used as an ordinary wagon-body.

Though I have shown and described a special lever construction for manipulating the chute A it must be understood that the invention is not limited to this construction, as other forms of levers may be employed without departing from the spirit of the invention.
